[PATCH]: Re: KDB updates

[linas at austin.ibm.com]

Paul,

I don't have bk push authority to ameslab, can you commit the attached
patch from Ananth?  (unless Ananth writes back and says 'stop don't do it')
I tested it on power3, it handles user-space stacks much better, and also
fixes my '10 seconds to enter kdb' complaint.
